To be honest I was very close to returning this trumpet, but at last I must say it is a very good product in the sense of value/price, and I have one of my dream (playing a C rotary trumpet, like the guys in Berlin philharmonic I watched since I was a kid) come true. When picking up this trumpet, as a amateur piston trumpet player I almost cracked every note on it and find the sound dull and not vibrating, like the sound of a cheap oboe. I try many mouthpieces and struggle to get used to it. It get better and better gradually. So I decide to keep it. Well, the next cheapest C rotary cost around 3,000 EUR, so, thank you Thomann, for making my dream come true. I well keep it and get along with it, long term.
